This video analyzes the Ukrainian drone attacks on Russian air bases, explaining why Russia was largely unable to prevent them. The analysis focuses on the limitations of Russian air defenses, the strategic advantages of the drones used, and the logistical challenges faced by Russia in protecting its vast network of airfields.
According to Ukraine, 117 small quadcopters were used across four locations. Images of trucks suggest 30 to 60 drones per truck per air base.
The Ukrainian drones flew at low altitudes (1-2 meters above ground) and at relatively slow speeds (around 50 kilometers per hour). This allowed them to avoid detection by radars programmed with threshold filters designed to reduce false alarms from things like car traffic or birds. The slow speed also meant that even if detected, there might not have been enough time for a meaningful response.
Ukraine used commercial satellite imagery for daily reconnaissance passes to identify targets. They also utilized indirect routes (possibly via Kazakhstan) to smuggle drone parts into Russia, assembling the drones on-site in Russia to avoid detection. Some parts might even have been 3D printed locally.
